Whats the motive for a father to kill his own child. understand there is no motive. if the father has illegal relationship the person who is going to get affected is his wife and not daughter . So if wife would have been killed or something like that then we can look at it like that. the motive looks so stupid for me to kill somebody leave alone his own daughter. i bet its going to be hemaraj was the target and arushi was incidental.
